Abstract

The present invention relates to an implant system that comprises an implant, a handle configured to removably receive the implant, and, in some embodiments, a spacer tool configured to be mounted on the implant. In further embodiments, a k-wire is employed to guide the implant to a desired location. The handle has a hole for receiving a first portion of the implant. Using the handle to implant the implant, along with an associated spacer, provides a quick and convenient method for implanting the implant as described herein and in the associated drawings.

Claims (36)

1. A system for connecting two bones comprising:

an implant including a flat land, a slot, and defining a passageway configured to accept a k-wire; and

a handle configured to be grasped by a user for inserting the implant into a first bone, the handle including;

a body having a proximal portion that defines an oval opening with at least one substantially flat surface of the body;

a hole defined by a distal end of the handle configured to receive a portion of the implant, the hole being further defined by a divider sized and configured to be received within the slot of the implant so as to orient the implant such that the substantially flat surface is aligned with the flat land of the implant when the portion of the implant is received within the hole;

wherein the handle is configured to be removed from the portion of the implant after inserting the implant into a first bone portion.

2. The system as recited in claim 1 wherein the implant is arranged in a predetermined orientation when engaged by the body within the hole.

3. The system as recited in claim 1 wherein the at least one surface is aligned with at least one wall that defines the hole and the flat land of the implant.

4. The system as recited in claim 1 wherein the k-wire is arranged so as to pass through the implant to thereby guide the implant.

5. The system as recited in claim 1 further comprising a removeable spacer secured to a portion of the implant.

6. The system as recited in claim 5 wherein the spacer is configured to prevent insertion of the implant into the first bone portion beyond a predetermined distance.

7. The system as recited in claim 5 wherein the spacer is configured to prevent insertion of the implant into a second bone portion beyond a predetermined distance.

8. The system as recited in claim 2 wherein the handle further comprises a landmark that corresponds with a preferred orientation of the implant.

9. A system for correcting a hammer toe by fusing a middle phalanx to a proximal phalanx, comprising:

an implant having a slotted first barbed portion, a second barbed portion, and a flat land;

a handle having a body that defines a divided hole configured to receive the first barbed portion, a proximal portion of the body having an oval shape defined by at least one substantially flat surface configured to be received within the slotted first barbed portion and wherein the substantially flat surface is aligned with the flat land of the implant when the first slotted barbed portion of the implant is received within the hole;

a removable spacer coupled to the implant, the spacer comprising serrations and a dimple configured to form an interference fit with the implant, wherein the second barbed portion is configured to be secured within at least one of the middle phalanx and the proximal phalanx and the first barbed portion is configured to be removed from the handle and then inserted into the other of the middle phalanx or the proximal phalanx.

10. The system as recited in claim 9 wherein the implant is defined by an angle formed between the first slotted barbed portion and the second barbed portion.

11. The system as recited in claim 9 wherein the implant defines a cannula having a passageway configured to accept a k-wire.

12. The system as recited in claim 9 wherein the second barbed portion comprises a plurality of barbs forming a thread.

13. The system as recited in claim 9 wherein the hole of the handle is further configured to prevent the implant from rotating when the implant is secured within one of the at least middle phalanx and the proximal phalanx.

14. A method for locating an implant between a first bone and a second bone portions, the method comprising:

providing an implant including a flat land, a slot, and defining a passageway configured to accept a k-wire;

providing a handle configured to be grasped by a user for inserting the implant into a first bone, the handle including;

a body having a proximal portion that defines an oval opening with at least one substantially flat surface of the body;

a hole defined by a distal end of the handle configured to receive a portion of the implant, the hole being further defined by a divider sized and configured to be received within the slot of the implant so as to orient the implant such that the substantially flat surface is aligned with the flat land of the implant when the portion of the implant is received within the hole;

providing a spacer configured to be removably coupled to the intermediate portion of the implant, wherein the spacer comprises serrations;

positioning a portion of the implant within the hole of the handle, such that a user can grasp the handle and manipulate the implant with the handle;

inserting a second portion of the implant into the first bone portion;

removing the handle from the first portion of the implant; and

positioning the first portion of the implant within the second bone portion.

15. The method as recited in claim 12 wherein the implant has barbs on the first portion and on the second portion.

16. The method as recited in claim 12 wherein the hole is configured to hold the implant in a predetermined orientation.

17. The method as recited in claim 14 wherein the handle has at least one orientation surface that defines the orientation of the implant.

18. The method as recited in claim 15 further comprising using the orientation surface of the hand to orient the second portion of the implant with respect to the first bone portion.

19. The method as recited in claim 14 wherein the implant is a cannulated implant having a passageway therethrough, and wherein the passage is configured to accept a k-wire.
